Everyone reading this most likely knows that the ice in the Arctic is melting – much faster and sooner than expected or predicted a few short years ago. Many of you may know that within only years it will all be gone during summer and that the physics of the earth system dictates that this is a truly fundamental and far reaching change for a number of reasons grounded in basic physics – albedo and latent heat to name two in particular.

Some of you may also be aware of the poorly understood but potentially even more catastrophic threat posed to the earth system by methane clathrates – and a few of you may be aware of the significant and growing list of positive feedbacks that are now underway and moving closer to dramatic and abrupt step changes. We know – whether you think it will take five years or fifty years – that our interdependent and logistically complex civilization is on track to face unprecedented challenges that history teaches us have an excellent chance of destroying it. We also know that the foundations for civilization will be destroyed in the foreseeable future – the stable benign climate that nourished us for the last ten thousand years will be gone for the rest of human history if truly dramatic actions are not taken immediately.

While I have some appreciation for how fundamental and serious this situation is – this is not a point I intend to dwell upon. I would like instead to talk about psychology – particularly yours.

While I am sure some people who read this may be already doing extraordinary things to try to address the situation – it seems a fair assumption to me that most will not be. Too many people are satisfied to wring their hands about the hopelessness of the situation and to become absorbed by the idea of their personal powerlessness. They look to the leaders of the political and corporate worlds to protect their own interests while perhaps failing to understand that these people look after their own interests first and foremost. The person best able to look after your interests is usually – you.

Too many people want to believe that a token sacrifice is enough to be able to say they did their bit to save themselves and the children of the world from hell on earth. Unfortunately using energy efficient light bulbs, recycling and offsetting carbon dioxide for flights and things is not enough to fundamentally change the situation. It is a good start and should be lauded as such – but even if everyone did these things – we are still damned – and therefore must appreciate that a greater effort is required.

What I want to do is to talk about personal responsibility. The actions of the collective masses of society including corporations and politicians start with individuals. If you cannot act proportionately to the problem to look after yourself and your family if you have one – how can you expect other people to do so?

My basic point therefore is that most people, even well informed people, are not acting to address the problem proportionately to the severity of the problem.

My second observation is that many people immediately destroy their own chances of greater action by various excuses that they use to destroy their effectiveness before they even tried. There is no surer route to failure than to never try in the first place!

If someone suggests to you that you communicate your concerns regularly to politicians and corporations by using telephones, letters and internet forums – do you start to do this or do you say that your voice is too little and that it would be a waste of time? Imagine for a moment the difference between everyone assuming it is a waste of time and countless millions of people deluging those with the power in our society with their demands?

If someone suggests you go on protests and demonstrations to highlight the issue and face arrest – do you say that you can’t take that risk, implicitly saying that you do not think the cause merits it? It is easy for the authorities to arrest a few hundred people – but again – they cannot arrest millions.

Do you tell people that the mess cannot be fixed and that geoengineering is bound to fail because we already made so many mistakes as a species? Do you justify ignoring the problem as you are happy to conclude it is hopeless and insoluble? If so, do you accept the idea that you are actively condemning yourself and your family and other people around you with whom you could cooperate to realize a better chance of a future – if only you stopped being defeatist from the outset?

I am saying that now is an excellent time to take stock and to realize that the keys to defeat and therefore victory lie first and foremost in your own mind.

I am not giving a prescription for any specific action – merely to point out that almost everyone reading these words can act more on these issues.

Here are a few notable examples of people I would say are acting in ways many people would conclude to be impossible and dismiss even the thought of attempting:

The author of this blog (http://jasonexplorer.com/about/ ) travelled all around the world using only muscle power taking over 13 years and travelling over 46,000 miles. He started as a virtually unemployed window cleaner and made it an awe inspiring platform from which to talk about sustainability.

Then there is the author of this blog (http://climate-change-action-plan.blogspot.com/ ) and many other blogs working tirelessly and without personal reward to educate and inform people. He makes sure not only to explain how serious the problem is but also to inform people of the solutions that we may still have a tiny amount of time left to implement to provide a collective hope for the billions of people living today.

Finally there is the author of this blog (http://deusjuvat.wordpress.com/about/ ), who is working on a plan that tries to face the consequences of civilization failing and promoting an aspiration to ensure that even in the very worst outcomes there remain some hopes for a future for our species. This starting from a position as a minimum wage worker.

I believe that the difference between an ordinary person and an extraordinary person is quite simple. In most cases it is quite simply the difference between being prepared to act and preferring to conform to the mold defined by social expectations where authority and responsibility are meekly delegated to other people.

We face an extraordinary challenge and we need extraordinary people to face it.

As the above image shows, a minimum volume of 3000 cubic km is expected to be reached in September 2013 (red dotted line), with a margin of error that allows for the sea ice to disappear altogether in a few months time.

Greenland Melt

Meanwhile, the National Snow and Ice and Data Center (NSIDC) has started a page with daily updates of the extent of the Greenland melt. The image below pictures the Greenland melt in 2012 on the left, and the situation up to February 6, 2013 on the right.

Dr. Leonid Yurganov kindly shared an overview of his analysis of IASI methane levels over the years.

The overview shows a marked difference between methane levels in the Arctic and methane levels at lower altitudes, i.e. between 40 and 50 degrees North. Furthermore, the overview shows a steady increase in methane levels over the years, both at high latitudes and at lower latitudes. Over the Arctic, mean levels of well over 1900 ppb are now common.

The overview gives the mean values for methane levels. Peaks can be much higher. Levels of up to 2241 ppb were registered above the Arctic at 742 mb on January 23, 2013 (see earlier post). Moreover, high levels are registered over a wide area, particularly over the Barents Sea and the Norwegian Sea, which are currently free of sea ice (see earlier post), indicating worrying releases of methane from the seabed in that area.

How much extra methane is released to account for this rise in methane levels? Dr. Yurganov explains: “this may be a relatively slow process, 7 ppb per month for the area between Norway and Svalbard means only 0.3 Tg per month. But in a longer time scale (at least several years) and inclusion of the autumn Kara/Laptev emissions it might be very important both for the methane cycle and for the climate. Further discussion promises to be fruitful”.

Dr. Yurganov plans to update his overview on completion of further analysis of existing data of IASI methane levels for earlier periods, and complemented with further periods in future as the data come along.

Meanwhile, we'll keep a close eye on methane levels in the Arctic, particularly given the prospect that large areas of the Arctic Ocean (Kara Sea, Laptev Sea and East Siberian Sea) will soon become free of sea ice. Further people analyzing methane levels are invited to also comment on the situation in the Arctic.

Above image shows dramatic increases of methane levels above the Arctic Ocean in the course of January 2013 in a large area north of Norway.

Why are these high levels of methane showing up there? To further examine this, let's have a look at where the highest sea ice concentrations are. The image below shows sea ice concentrations for January 2013, from the National Snow and Ice data Center (NSIDC).

Overlaying methane measurements with sea ice concentrations shows that the highest levels of methane coincide with areas in the Arctic Ocean without sea ice. This is shown on the animation below, which is a 1.84 MB file that may take some time to fully load.

Global temperatures are rising fast. In the Arctic, temperatures are rising even faster (interactive charts below and right). For 2010 and 2011, NASA recorded anomalies of over 2°C at higher latitudes (64N to 90N), with anomalies of over 3°C at latitudes 79N and 81N in 2010.

For November 2010, anomalies of 12.5°C were recorded at latitude 71N, longitude -79 (Baffin Island, Canada). At specific moments in time and at specific locations, anomalies can be even more striking. As an example, on January 6, 2011, temperature in Coral Harbour, located at the northwest corner of Hudson Bay in the province of Nunavut, Canada, was 30°C (54°F) above average.
